[A new culture medium for growing yeast].

A new nutrient medium for growing Saccharomyces cerevisiae yeast has been developed using geothermal waters as the mineral source. These waters makes it possible to obtain a complete nutrient medium by adding only ammonium hydroorthophosphate. Such a medium also ensures the recovery of biomass with high biotechnological properties.

[The effect of culture media on the protein level in Saccharomyces cerevisiae yeasts].

A culture medium containing molasses, geothermal water and only one mineral addition--ammonium hydroorthophosphate is proposed for obtaining the biomass with a high protein content (about 40%). It is recommended to use the Coomassie reagent for quantification of the total protein in the yeast biomass.

[Characteristics of arterial blood pressure in children aged 10-14 years living in Novosìbirsk (data of a simultaneous epidemiological study)].

The authors reported the results of a study of BP levels in children aged 10 to 14 in Novosibirsk using a standard WHO method. Regional normal limits of systolic and diastolic BP with relation to age and sex were presented. The mean levels of systolic and diastolic BP were growing with age, particularly at the age of 11-12.
